A decent Fortran/shell interface. The problem with the supplied
interface (ishell) is that it reproduces the parents memory image.
Users at this site (COS) are heavily dependent on Fortran-callable
JCL for re-start capability. Rolling out a 5+MW job to do an
" IERR=ISHELL('assign <args> ')" is an unacceptable solution.
(Fortran-callable JCL also allowed access to our Mass Storage
System through local extensions)
Currently I am diving deep into the bowels ;-) of UNICOS to create a
socket for such a purpose. Good learning experience, but I'm
surprised that some type of solution wasn't part of the plan from
CRI.
I understand that BSD's "vfork" solves this problem, as opposed to
"fork" (which ISHELL uses).
